Skyrmion, a concept originally proposed in particle physics half a century ago, can now find
the most fertile field for its applicability, that is, the magnetic skyrmion realized in …

Directional transport and propagation of quantum particle and current, such as electron,
photon, spin, and phonon, are known to occur in the materials system with broken inversion …

When electric conductors differ from their mirror image, unusual chiral transport coefficients
appear that are forbidden in achiral metals, such as a non-linear electric response known as …

In noncentrosymmetric materials, the responses (for example, electrical and optical)
generally depend on the direction of the external stimuli, called nonreciprocal phenomena …

In chemistry and biochemistry, chirality represents the structural asymmetry characterized by
nonsuperimposable mirror images for a material such as DNA. In physics, however, chirality …

The critical current of a superconductor can depend on the direction of current flow due to
magnetochiral anisotropy when both inversion and time-reversal symmetry are broken, an …

Recent observations of topological meron textures in two-dimensional (2D) van der Waals
(vdW) magnetic materials have attracted considerable research interest for both …

The rise of two-dimensional (2D) crystalline superconductors has opened a new frontier of
investigating unconventional quantum phenomena in low dimensions. However, despite the …

Low-symmetry layered materials such as black phosphorus (BP) have been revived recently
due to their high intrinsic mobility and in-plane anisotropic properties, which can be used in …

Manipulating topological spin textures is a key for exploring unprecedented emergent
